Military service for CSRS purposes is honorable active service in the following uniformed services: Army, Navy, Air Force, Marine Corps, and Coast Guard and after June 30, 1960, in the Commissioned Corps of the Public Health Service, and after June 30, 1961, service in the Commissioned Corps of the National Oceanic and Atmospheric Administration and its predecessor agency.


Active duty in the various reserve components of the branches listed above is creditable for CSRS benefits. That is, service in any reserve component is creditable when the individual is called to active duty period only. Such periods include annual active duty training periods.
Note: When an employee performs annual active duty training service during which he or she is on military leave with pay from a civilian position, the period is credited as civilian, not military service.
A period of military service may be credited for retirement and death benefits purposes, subject to the following conditions:


  • The military service was performed before the date of separation upon which title to an annuity is based.
  • It was active duty.
  • It was not included in the computation of military retired pay, or if it was included in retired pay, the retired pay was awarded based on disability incurred in combat with an enemy of the United States or caused by an instrumentality of war and incurred in the line of duty during a period of war; or granted under the provisions of chapter 67, Title 10, of the U.S. Code.
  • It was honorable service.
  • A deposit is made for post 1956 military service as required. The requirements for a deposit are dependent upon whether you were first employed before October 1, 1982 or after that date. The specific rules are identified below.

For periods of active duty service prior to January 1, 1999, the deposit equals 7 percent of base pay (not including allowances earned during the post-1956 military service). For periods of service performed during 1999, the deposit equals 7.25 percent, during 2000, the deposit equals 7.40 percent, and after December 31, 2000, the deposit is 7.00 percent of base pay (not including allowances earned during the post-1956 military service).


The earliest interest begins to accrue is October 1, 1986 or your third anniversary of entry into a CSRS position. Interest is compounded annually based on the same rate as for civilian deposits. No interest is charged if you make the deposit, paid in full, before the first interest accrual date.


Interest is charged at the same rates applying to deposits or redeposits to capture civilian service. *
